R1 Concepts 623-80064L RNC Series Drilled Brake Rotor

The R1 Concepts 623-80064L is a RNC Series drilled brake rotor engineered to deliver reliable stopping power and improved thermal performance over stock replacements. R1 Concepts manufactures this rotor using premium G3000 grade cast iron, ensuring consistent bite, fade resistance, and long service life under demanding driving conditions.

The precision-drilled hole pattern serves a dual purpose: it allows heat, gas, and debris to escape from the rotor surface during braking, helping to reduce brake fade and keep rotors running cooler during spirited driving or towing. Each rotor is computer-balanced and finished with a zinc-dichromate coating on non-friction surfaces to resist rust and corrosion during storage and on the road.

Key Features:

• RNC Series drilled brake rotor for enhanced heat dissipation
• Premium G3000 grade cast iron construction
• Drilled hole pattern reduces heat buildup and brake fade
• Zinc-dichromate anti-rust coating on non-swept surfaces
• Computer-balanced for smooth, vibration-free braking
• Direct OE replacement fit — no modifications required
• Manufactured to strict dimensional tolerances for proper caliper and pad alignment

Designed as a direct-fit replacement, the R1 Concepts 623-80064L installs using factory hardware with no drilling, cutting, or modification required. Compatible with OEM and performance brake pads, this rotor is an ideal upgrade for drivers seeking improved brake response and a cleaner, more aggressive rotor appearance.
